Herein, we propose a novel method to create multidirectional and multilevel pointing input using only a hardware keyboard. The relative position vectors among pressed keys are calculated into an input vector. The pointing performance of this method is evaluated based on the ISO 9241‐9 recommendations. We find that the performance of the method is sufficient to create moderate pointing input, as the measurement of the throughput is close to that of a touchpad, as measured in past studies also using the ISO 9241‐9 recommendations.
